Clicking on a suggested tag when retagging a question cancels the retag

edit

1. I clicked on the retag widget to retag one of my questions.
   • The list of tags turned into a text input as expected.
2. I began to type a tag.
   • The list of suggested tags appeared as expected.
3. I clicked on one of the suggested tags.
   • Expected: The suggested tag is added to the text input, replacing the partial tag I had typed.
   • Actual: The text input disappeared, and the previous list of tags appeared in its place as if I had pressed the escape key or otherwise canceled the retag.

I'm using Chrome on Mac OS. Let me know if you need additional details.
